While we're discussing preamps for $79.95 new, have a look at this: <http://minicircuits.com/pdfs/ZX60-33LN+.pdf> At 1 dB The NF is a bit higher than the ARR/Angle Linear GaAsFETs, but check out that +18 dBm P1dB! And the bandwidth: you can keep it as a spare for your 6, 2, 220, 440, 900, 1.2 or 2.4 GHz repeater! At 21 dB gain, you might need a few dB of attenuation after it if you're feeding a non-commercial quality RX. The only drawbacks to this unit are the 3 or 5 V power requirement (78L05s are cheap though) & the SMA RF connectors. BTW if you do need a pad on the output here's a good, cheap selection: <http://minicircuits.com/products/attenuators_coax_fixed.html> Scroll halfway down to the "VAT" collection: $12 ea., take your pick.
