There is nothing magical about a front end saver, IMHO.  Several years ago I 
built my first, a simple unit employing a pair of Panasonic PCB-type relays 
which grounded both the RX antenna port on my transceiver and the beverage 
antenna input to the preamp/switching system on transmit.  As long as you do 
not intend to use full break-in this system works very well and costs peanuts 
to build; after some 15 years running a KW or better no problems have ever 
occurred, and I have duplicated this simple design at other stations.

Of course, you can build a fancier unit which will handle full break-in and 
perhaps have a few bells and whistles included, but the basic unit will serve 
the purpose for most hams running separate antennas for RX and TX.
