If you have good luck with them then stick with them but check out the seedbank ratings here and ask yourself why Attitude got 2 stars and why some seedbanks got 4 or 4 1/2 stars.
There has to be some reason.

Dude I can put up a more professional looking "seed bank review" site in a day. I'll go with my thousands of dollars worth of happy biz with Attitude over some anonymous poster's halfass seed bank review site any day. That site is almost as ridiculous as the original poster's "trust me I have good reasons" comment.
