I bought one from Apex last year, it was in fairly decent shape. It's currently with Arizona Response Systems being built and refinished. I also bought one of the complete Officer model rifles that DSA built.
The question is if the ones PSA has on clearance are bottom of the barrel or not. I've heard of some people that got really nice ones in the last couple of months, and some that were pretty rough. Might be down to luck of the draw.
If you want one, I'd probably go ahead and give it a shot. If you decide to not go ahead with the project, you could probably get your money back selling the parts after the kits are not available any more. Also, up until this last batch of kits came in within the past couple of years, the Israeli stuff was pretty rare.
