Is there an affordable way to park near PHX during an 8-10 week trip?

Perhaps in a off-site parking with really good long-term rate, or a hotel that offers parking (with or without an overnight), or something with a monthly rate, or even a storage unit lot? Either with a shuttle or maybe a cab if very near. Don't care if it's covered or not (this is for February and March).

By affordable I mean a target of $150 a month or ideally less. I do have some other options involving shuttle buses (not very nearby) and overnights or expensive regional flights (that would still need parking), but it would be handy to just drive and park near one of these airports.
