I would look for a 90's mountan bike with a chromoly frame and put hybrid tires on. I currently have a Trek 830 but there are other good bike brands as well . Look for one with shimano parts as bike shops have lots of Shimano  replacement parts.

NOT !!

There is no really "quality" difference between different levels of Shimano or SRAM components. The cost difference is due to volume and lightness (lighter = more money). A $15- TX55 RD will last as longer, probably longer than a $90- Deore XT RD. The XT is around 2/3rds the weight, Shimano makes and sell a hundred or more TX55 models for every XT.
