I like both Universal Laser systems and Epilog. Both have a 'trophy shop' model that is probably under $4k. I personally went with the ULS and the deciding factor was the rotary fixture. For the type of hollow vessels I was turning, it seemed to work better. The other thing to look at is table size, but the price of both models goes up with that. In both cases, even the small models have enough laser power to do leather. A mere 20 watts is all that is necessary to engrave leather. Ok, now metals like brass is a different matter. At <50 watts, metal can be marked (as in the serial number tags attached to any electronics these days). If you actually want to engrave (cut/remove) metal, you have to step up to one of the larger models that include a beam compressor. Basically, it puts more heat at the same point with the same amount of power. This is done by changing the frequency of the laser beam and some fancy optics. this really moves the price of these from the 4 digit range to the 5 digit range. Hope that helps.
