I'd rather get reconditioned than cheapo.
You just don't know what you're getting from cheap injectors - I'd probably buy six knowing that two might be faulty
Reco 12 hole aren't that expensive - well worth the improvement Jeep owners report.
I think late model Toyotas are four hole - should be able to get low km used ones.
There are also services that reco injectors that can make up direct fit injectors so you don't need piggy back harnesses.
You car should run fine with single hole injectors but possibly slightly less efficient. I wouldn't go backward personally when there are so many upgrade choices.
