Dunno. I have only seen a couple for sale for the last couple of years. I got a Rocket RT but it cost me a bundle.
Same actually goes for Rocket blue tips.
I got a user grade red tip rocket for under $100 USD with international shipping but in the main the last few I've seen that have shown up for sale on the bay went for above $100 USD.
Buying lesson, when they say no international shipping, buy it anyways and ask them to quote you a shipping cost afterwards. The seller is not going to cancel the sale 9 out of 10 times if you are paying the shipping.
