SH .28 is NOT a good motor. save your money there.

I say get a Picco .27 they are like $150 new and are really decent. Otherwise the Mach.28 is another good choice if it's anything like the mach.26...great budget motor that really moves, tunes well and last a long time.

Maybe look for something used? I just sold my Eb mods Novarossi P5 ($350) for $150
