My advice is if your gonna buy an engine, get one that you can see first hand and inspect. People who buy things and hope for the best that itll work out for them are the kind of people who gets themselves into situations that they shouldnt have been in the first place. Thats what you sound like right now. If you cant afford to do basic maintenance on an SR before you install it and do it right from the get-go, youre better off sticking with your KA till it either blows or you save enough money to do your swap right.

And honestly, the chance of you getting a good engine is getting slimmer by the day. There aint a whole lot of clean SR swaps coming out of japan since supply just couldnt keep up with the demand. Most of the clean ones have already been plucked, the ones left are less and less quality compared to 2 yrs ago. So heed my advice when I say find somebody local. Why? If something is fucked up on it, you can just drive back, let them know and hopefully get replaced on the spot.

A better question for you isnt redtop or blacktop. Its whether you should get an engine set or a clip. Engine sets are cheaper and some places actually would sell you everything you need for your swap with their engine set. Basically your getting a clip without the damn clip.
