Several problems with low band for linking. First, directional antennas can be unwieldy at lower frequencies, and most links are done with yagi-style antennas. The second is skip interference, which could cause a host of problems if you're using a low band channel to control a VHF or UHF repeater.
Its sad to see manufacturers abandon a group of frequencies that work so well in suburban and rural areas. Low band gives so much bang for the buck, and VHF Low radio systems are so simple and bulletproof, they're almost tailor-made for public safety and critical infrastructure radio systems in wide open areas.
Motorola, Vertex and Kenwood have a handful of VHF Low stuff available, and you can find some pretty good deals on eBay. If you do the eBay or used equipment route, be aware that low band radios usually come in "splits" (30-36 MHz, 36-42 MHz and 42-50 MHz for most Motorola equipment) and you'll need the correct split for your operating frequency. The 30-36 MHz radios are becoming particularly hard to find nowadays.
