Dead Ht1250, HT750, & EX600

[tcash158]

I have a dead HT1250 an HT750 that will not turn on with any battery I put on them, the Motorola shop and another radio shop have told me that the main chip in both radios are bad and they have to be sent to Motorola and its a 300.00 flat repair each. I also have a EX600 that the keypad quit working and the shop thoght it was a bad flex cable and replaced it and it didnt fix the problem so they didnt charge me of coarse but said it had to be sent back to Motorola for repair and it would also be 300.00. Is there anywhere else I can send these to get them repaired that would be any less?
