You should be able to find these within your budget. The main "gotcha" is that Tamron does a very shaky job of identifying its various models of similar lenses. The Tamron 90 macro has had a multitude of incarnations, all good but some predating the inclusion of the BIM (built-in motor in Tamron-speak) which is necessary for auto-focusing to work with either of the lines of Nikon cameras I'm suggesting. Most of them will have the BIM, as that was added across the line a half-dozen years ago. But make sure before you buy. You will also want a tripod and some form of remote release (I like cable releases, some prefer the IR kind). The tripod may or may not fit in your initial budget. FWIW
