Have had 2. Spent good $$ on both but one I bought for more cost less, ie the mods were already there - forgie, suspension etc. Just tidied it up to suit me specifically - no worries ever.
Other one I bought cheap also forged - this I spent a fair amount of coin to bring it to the cosmetic standard I was after - mechanically though, was mint.
Moral, get a forged one thats already had loads spent on it. The first one I had is for sale if asked about I think... Owner is in NSW. Since I sold it to him, he's rebuilt turbos with stronger internals (-5s), new clutch (hks twin plate couldn't handle power at high revs apparently..) and other stuff. He wants 30k though. Shell done 67-70kish, motor 7-10kish, no rust no dents. Currently making 520-540ish rwhp from memory. My point is, I bought that car for 17.5k and the engine, excluding everything else cost $18k to build.
Just keep hunting.
