I have two friends that have gone the 1uz route (both of whom had their cars impounded and neither of them got a ref ticket). One of them had multiple LS swaps previously and both of his LS motors had issues. He has had his 1uz swap for years. It starts up every time and he beats the piss out of it. He uses a stock K tranny, which means both motor replacement and tranny replacement would be cheap. RubyS14 said it best when it comes to adding power to the 1uz, though. If you aren't satisfied with the stock power output of a 1uz you're probably better off going LS and starting with a cheaper iron block to help keep costs down. I'm pretty sure you need a stand alone to tune a 1uz and good luck finding someone who knows what they're doing tuning it whereas with an LS you'll start out with more power and have cheaper tuning options. It's a cost and reliability vs. power decision really. Also, I believe header routing is easier with a 1uz.
