I haven't grown much from them, but have only heard good reviews. I grew one of their AK's which was nice for an AK type plant. I heard they source their beans from other breeders. Meaning since most beans are produced in europe, they just buy these beans where they are produced for bulk discount and sell to everyone.
I don't know what your budget is, and I don't know how many plants you are wanting to run. But since you only have a small room I think 5 plants would be plenty for you. Grow them in a 5 gallon bucket using good soil if this is your first grow - just makes it easier and less room for error. Or 3 gallons if the 5's are too big. I'd say you are new to growing, but I am just guessing there and don't mean to sound like a dick or anything. But if so, this grow can go smoothly if you just simplify everything and don't overthink it like most do their first time or 2. Don't worry about getting the best, just worry about doing the best you can and learn from it.
For strains I would go with something that stays fairly short, or don't stretch very much that way you don't have to learn as much about LST and super cropping etc your first round. But then again, it isn't that hard if you choose to do so and greatly increases your yield.
For Female Seeds look at BubbleGummer, Pure AK, White Widow x Big Bud, and if you don't mind a little stretch look at C99 and Grapefruit which are awesome! My first pick there would be C99 if you can manage the stretch and don't mind the work, 2nd choice would be Pure AK for ease of growth and all around plant. $7-10 each, $25-35 for 4.
For Vision I would look at AK49, Northern Lights, Critical Impact, Chrystal queen, cheese, bubble yum, super skunk. For them my first choice would be Northern Lights or AK49. Both should be easy grow. Around $7 each, or $30 for 5
Pyramid might be your best bet all around tho. I would get Tutankhamon, and/or Anestesia. The Tut is an AK plant and everyone says is from the original AK47 from years ago and is the best you can get. The Anestsia is a very indica strain that is a heavy stone. Around $10 each, or $40 for 5.
Nirvana has many great strains. Ak48, Blue Mystic, Aurora Indica, Bubbleicious, Northern Lights should all stay fairly short and even and be great choices. They are $8 each or $40 for 5.
Also G13 Labs Pineapple Express is a GREAT strain for a first time too. It is pretty good smoke, not elite but it is good. And it also yields great, and is one strain that is super easy to grow in almost any condition. I have grown quite a few of these over time. They are $10, or $45 for 5.
And I really like Humboldt Seed Organization for cheaper Fem seeds. Their Blue Dream is a great plant, and would be my first choice out of everything if you can afford them, and don't mind topping them a few times and dealing with their stretch. They are $12, or $53 for 5. Also others to look at are Desert Disel, Green Crack, Pineapple Skunk, and sour blueberry, and trainwreck. Their Pineapple skunk would probably be the easiest to grow and yield very well, and the sour blueberry being a close 2nd. The pricing on those 2 are $10-11 per seed, or $41-48 per 5 pack.
If you have anything in particular you are looking for I can help you more. I was just finding what was the cheapest strains that I knew would make for a good easy grow. Out of all of these listed here my first choices would be HSO Blue Dream, or maybe FMS C99 if you could handle the stretch of them. But for a honestly easy easy grow I'd probably go with HSO Pineapple Skunk, or G13's Pineapple Express, or any of the Ak and Northern Light strains.
