ermmm .... seeing as how the 2 digits of the Visar aren't enough, as kindly pointed out by Grog. You might look into any one of these:
MT2000 Model II or better
MTS2000 Model II or better
HT1250
HT1550
XTS2500 Model II or better
XTS3000 Model II or better
[EDIT]Oops, forgot one ... XTS2500 too. You can forget not paying out the rear for a multi-line radio (which are the higher-end radios to begin with). I put one-line radios in there, because as your gonna find, all the multi-line radios are a little, well, out of your price range.[/EDIT]
