I've had an MVT7100 for maybe 5 or 6 years now and has served me well. It's starting to go a bit senile now in its old age though. It was bought for £250 and the telescopie aerial was free with it, last time I checked the price of a new one it had held its price pretty well compared with most other electronics I had bought.
It has a superdooper scan rate, but I think all models had an internal noise or 'birdie' around certain frequencies, including 129Mhz which is particularly annoying.
