I have one of these. Surplus! Last two sold on US eBay made $26 and $31 plus the postage.
That's an average for the two of $28.50 so at $1.60 = £1.00 makes it £17.81. I see that the plastic ones are £14.00 on Midway UK!
The thing weighs a fair amount and is quite bulky, so it's package rate not letter. So I guess that takes the postage to about £3.50 or thereabouts with the Recorded Delivery at Second Class Rate.
If you want it is yours for £21.50 certainly an "all in" cost less than it would cost to get one from the USA.
However it isn't a "magic bullet" and although it is nice to have be aware that it may not possibly fit LATER RCBS Rockchucker presses....only the earlier crinkle green finish ones.
Will send PM shortly
The ONE that I did have is now sold to KLENCHBLAIZE and I don't have another.
