Without getting into the debate on Part 90 vs 95 figured I'd list some basic Repeaters for UHF that would be good base units if your shopping for new.
Low Power
RT97 - List Price - $536 (Sale Price - $371.99) - https://www.retevis.com/rt97-portable-gmrs-repeater-mobile-repeater#A9150CX1
Midland MRX10 - List Price - $ 459.00 - https://midlandusa.com/products/midland-mxr10-repeater
Mid Power
Bridgecomm BCR-40U - List Price $1499.00 - https://www.bridgecomsystems.com/collections/amateur-radio-repeaters/products/bcr-40u
ICOM FR6300H - List Price $1819.00 - https://theantennafarm.com/shop-by-categories/radios/repeater-systems/uhf-repeaters/11680-icom-fr6300h-detail
Kenwood NXR-810K - List Price - $1770.00 - https://theantennafarm.com/shop-by-categories/radios/repeater-systems/uhf-repeaters/9640-kenwood-nxr-810k-detail
Motorola SLR5700 - List Price $ 3700.00 - https://theantennafarm.com/shop-by-categories/radios/repeater-systems/uhf-repeaters/9581-motorola-slr5700-detail
To be noted none of the mid power repeaters come with a duplexer. That will tac on another $300 and up depending on what you purchase.
Granted there are many UHF part 90 repeaters used on the market that can be had for way less money than above but wanted to list new prices. If your searching online and someone is advertising a GR1225 on GMRS for $1000 I'd think twice. For mid power I have no experience with the Bridgecomm or the new NRX (however have many of the older Kenwood) units. Just wanted to put some info in one location.
The low power units are nice because they basically work out of the box. I also realize the prices on the mid power units look high when your comparing to some of the CCR world but they will outlast pretty much all the home brewed stuff as they are built to do what they are.
Some used older stuff that can be had reasonably are the Vertex VXR Series, Motorola GR1225, Motorola MTR2000, Motorola Quantar, Kenwood TKR850, Midland Base Tech II (Was a solid unit), ICOM FR4000 and the Motorola XPR series.
