Might just be me, but I've had great luck with my WE glock. Considering it was a machine pistol model and I put more than 5k rounds through it without a single problem before I sold it, I think.
I would personally stay away from WE hi capas though....even with a jury fixed midframe it still had many retarded problems....you might even be able to find my thread regarding with that lol
My KWA M93R Special Ed. is a heavy piece of block, but has lasted a good 8000 rounds. The only "problem" with it is that it reached the gas cooldown point after just two magazines and holsters are....non existent.
I would recommend a Tokyo Marui Glock or WE Glock if you can't afford a TM or if that isn't your flavour then a TM Hi Capa. Can't go wrong with a TM and with literally tons of aftermarket parts!
