Hanzo, go check out the falfiles forums.
www.falfiles.com/forums, and go look in the marketplace. There are usually some very nice FAL rifles out there for under $1000. Once you try out a FAL everything else is just a gun.
I personally own SEVERAL now after buying my first in July. Two of them I built myself. Parts kits are drying up fast, the recent nice IMBEL kits that were out there over the summer have pretty much sold out and there are no more StG kits from Europe or L1A1 kits from Aussieland coming ever again. Somebody has some Rhodesian South African kits they unearthed going for cheap but that's probably the last SA kits we will ever see.
Entreprise Arms (Note odd spelling of ENTREPRISE) has a reputation for poor customer service and spotty quality. They have re-invented themselves lately and are promising receivers & finished rifles that are good. We'll see.
Century Arms Int'l have a reputation for quality issues but their recent crop of receivers is made by Caspian Arms and is actually quite good. CAI's gunsmiths tend to slap things together without the finer points of fit and finish. Measure with a yardstick, assemble with a sledgehammer, fit with a hatchet, sand with a chainsaw, paint with a bucket. Great if you are building totem poles not so good with rifles.
Hesse receivers had as much trouble as early Centuries did. Not an asset.
IMBEL receivers were imported from South America and it is often amusing that we take a brand new IMBEL rifle and remove the chopped up IMBEL receiver and put a new one right back on. However IMBELS are getting up towards $500 each for some reason.
DSA receivers are the "premium" US made FAL receiver and you will pay for that as well as wait in line to buy one. Prices are almost as high as IMBELS.
Williams "Alumabomb" receivers are best taken straight to the recyclers.
Coonan receivers (DCI) are now being re-introduced by NodakSpud. Supposedly they are very nice.
Ohio Rapid Fire will be introducing an all new FAL receiver... soon? But it is brand new so YMMV as far as quality. May be nice. We'll have to see.
