I've actually got a [Telegames] Quest For Quintana Roo, myself. I think it's actually my only NTSC Telegames cart. I don't know if I'd say it was cheap, exactly, but it certainly cost me a lot less than it could have.
My wife almost shit a brick when she found a copy of the Sunrise version at a thrift store. I felt kinda bad when I had to tell it was the more common Coleco version. The Sunrise version was a pretty expensive cartridge at the time, but, like a lot of rare 2600 carts, much more affordable now than they used to be (weirdly, it's the common stuff that's inflated in price...go figure!).
