While I have not had personal experience with Brimstone the positive feedback from many happy customers on RFC leads me to believe this is a great deal for the money.Brimstone Gunsmithing for a trigger job. They have 3 different trigger jobs available depending on what you are looking for. I got the cheapest job done for $35 including return shipping I don't think you could possibly find a better trigger for the money.
I agree if you are looking for value all of these are good options. But Kidd is the best if you have the money.IMO, I'd rather pick up a (slightly) used trigger group on eBay and send it off to GunDoc, Brimstone, or SwampFox and have them work their magic. Ends up saving $100+ and you get just as nice a trigger as one of the completely aftermarket options.
As the former owner of a VQ and Hornet trigger group I agree with both statements.Kidd is widely regarded as the creme de la creme and for good reason. After that there's the Jard which I really like and the VQ TG2000 which I'm not impressed with at all considering the cost. Have gotten better rebuilds for under $100 that were better than the $200 VQ one. The Hornet group doesn't really impress me much either as it's more or less just a reworked factory assembly. I'd much rather have one done by TT Shooter or Brimstone before going with a Hornet group. On the DY route, the Kidd again is at the top with their trigger job kit.
If you are in to modding your own trigger I'm also a fan of Skeeter. Check his website link below.
