I have a harmony 890 that I am wanting to sell since I got my harmony 1000 a few months back. What would be a good price to sell it at without the ir repeater (I am keeping it for the 1000) and where would be a good place to list it for sale? I was thinking $125 sounds fair but haven't seen too many others out there for sale.

list half, go from there

Since you are keeping the repeater you are hurting the price. Now you have to price it around a typical used price minus ~$99 since you are missing the extender.

I sold my 880 on ebay last week for $125 buy it now. It had about 30 minutes use though.
I wanna 1000 now.:)

I got screwed trying to buy a 890 on Ebay's Buy It Now option. I never received it! Luckily after Paypal investigation, I was credited the money back to me...Im still looking for a remote + extender though!
