With the receive-only preamp at $17 and the switching preamp at $125, you could blow up six of the receive onlies and still be ahead on cost.
I use a switching preamp because I use the same 70 cm antenna to work VO-52, AO-7 and the local repeaters. Would have been cheaper to use a receive-only preamp with one antenna dedicated to the FM LEOs and put up a seperate 70 cm transmit antenna for the other purposes. But probably the piece of mind is worth the extra money.

For idiot proofing, the switching preamp is a good idea. :)
