A simple search yields many answers. Unfortunately, the advice is scattered throughout many different threads. (Hopefully one comprehensive thread will be made soon).
But essentially, if you ask 10 people you'd likely get 8 answers. A lot of people talk about Gameness, Keiko, HCK, Sirius, Ouano, Fuji, Atama, and Padilla & Sons (
www.matrat.us). Except for the last one, I've found that Budovideos seems to offer the best price on all gi's. For the Padilla, you have to order straight from them.
And I also found a guy who makes a gold weave that gets them out for about $50 after shipping. Called Impact Fightwear. I don't have much to compare it to, but I like it.
People seem to agree that Atama is a great simple gi, but they hiked up prices so now people say for the money they no longer stand alone. Either way...10 people, 8 opinions. I think it comes down to sizing and what you want.
From my understanding on weaves...
Single: lightest, most durable, breathes well but not as good as gold.
Gold: a little heavier than single, but it's woven more loosely so it breathes better (i.e. sweat can dissipate better). Less durable than a single, but we're talking 2-3 years versus 4 years.
Double: heavy weave, much harder for opponents to grab, last the longest, but due to their weight most people just use them for competition so they can't be choked as easily.
Hope this helps, somebody please step in and correct me if I've misunderstood something.
