It really depends on what your looking for. i never found the UL's to be superior to say, the proto 2 piece, as they are made by the same company (used 20-30. I have found the Redz pepperstick to be very quiet on a rail, especially with the techt bolt they can be found for under 30 for a 14' and around $60 for the kit (4 backs 2 fronts). The critical 100g makes for a great barrel, light and accurate, although a little more pricey. a freak kit or deadlywinds freak kit will run on the upper side of your price point. there are also hundreds of old school barrels that people consider superior to today's barrels, mostly based on old barrel tests and such, but i have yet to see a Full Modern test that includes ALL the barrel options. I have a Huge collection of barrels, maybe someday ill find them all and find a scientific way to run a test.
