Don't think you could go wrong with the Graco magnum pro X7 airless, nice little painter, iirc, it has a repairable pump (packing's) which many cheap sprayers do not. "pump kits" or replacement packing's for my painters run about $40, but that is for commercial line painters. If you will use it to make side $, might consider stepping up to the x19, but either way, get one with a cart or stand, much easier to deal with.
Another great little sprayer on the cheap is the Krause & Becker and only $160 ish from harbor freight, get a coupon and get it even cheaper. We have around 100k in commercial sprayers and I bought one of these for our interior, only think I disliked was the small cart, it is built for 1 gal. but you can set it on some thing solid and use 5 gal buckets. What I like about this one is it has been fairly easy to flush after using and without a ton of waste.

Nice thing about Graco is parts availability, pretty much any Sherwin Williams has tips and hose parts as well as online
Always flush both the pump, line and reverse the tip and flush it as well. If it is a latex and you flush with water, make sure it is stored certainly dry during cold weather, or kept above freezing.
