The Reloader one is £180 inc delivery. He sells via another shooting forum. Technically there would be vat and duties on top of this though but that is paid by you on receipt. Maybe that is where the £220 number comes from?
Really depends how many you want to anneal and how fast. I know the caselife one has different wheels for different calibres - but the standard one works for most. The individual discs on the reloader are also for multiple calibres depending on the diameter of the rim.
Remember you need to add a torch too.
