Sorry I just can't see the $149.99
OK I know that they install it for you but you still have the shipping costs and it is no longer covered by Dell since it was repaired.
My point, if it is a damaged 300 MHZ machine, that is a given, buy another unit, sell your battery, stylus, cradle/cable, power supply etc on ebay or something.
If it is a 400 MHz unit, at $149, I would be willing to do the work myself. Again, order a 300 MHz unit. Sell the accessories that came with the original unit etc. You still have the case, buttons, CF dummy slot etc...
Here is my guessing
$15 for power supply
$35 for battery
$5 for stylus since so far only Dell Stylus work with this
$10 USB cable
$65 total taken from the $199 after rebate cost, its still $135 for a screen and you still have a new case once it gets scratched etc, or a button board for after you finish mashing the hell out of it playing games, a second lower port etc..
Just IMHO
