I think I paid $150-something for my Arrow II with the diplexer
(because I only use one radio) so yeah about the price of two cheap
Chinese HTs.

There is nothing stopping anyone from building an entirely adequate
antenna themselves.  See, for example,
http://www.wa5vjb.com/references.html .

SO-50, with the FM uplink on 2 m, I don't see much need for full
duplex and, in fact, I've had good contacts on a single radio.  I can
see where AO-85, with the FM uplink on 70 cm having a bigger Doppler
swing, that it would be very helpful to have an ear on the downlink.
For data, since most digis seem to be on 2m up and down, I don't see
the big deal.

On the sats with a linear transponder, it's a different matter since
you need to find where you are unless you are using a computer to
correct your at-sat frequency.

All that said, if you want this to be a cheap hobby, you're really
going to have to work at it.
