Not much...... for the kit (body + kit lens) probably $250 if u sell to a shop and about $300 if u sell yourself. I asked Alex Photo about a year back. The RC-1000 might be worth about the price u paid for........ the Sigma 100-300 f/4.5-6.7 probably is about $200..... the Minolta equivalent (non-APO, f/4.5-5.6) is going for around $275 (not fantastic condition)......
