Yes to the evolution saw, very good for price, mine has had years of abuse and still not mustered up to replace it. Blade choice is poor though,stock blade is good though for roughing and moderate work, teeth too big for anything with a surface on it though
Depends how cheap.
Reckon the Makita MT stuff is a good bet for DIY gear:

Or the regular Makita one with a slightly smaller blade:

If you want cheaper, I've always been pleasantly surprised every time I've used an Evolution saw:
