Feather Artist Club RG or DX, and what's the best UK prices?

In the UK I can purchase the RG for £120 or the DX for £210, but is the DX actually worth the extra £90? After all, neither razor is going to corrode.
Also, does anyone know anywhere I can get either at a cheaper price than those stated above? eBay has the DX for around £170 including p&p, but that's from US sellers and I'm guessing I'd more than likely get hit with import duties, taking the price very close to £210.
Presently I shave with a Mastro Livi Regrind and a Ragg, but want a travelling companion that I don't have to strop.

Here's the link where i purchased mine, a Artist club SS, a member i know quite well over on the shave den uses a Feather Artist club and a Feather RG which basically as the same head and face profile as the DX, but told me the Artist club shaves better than both the RG and DX.

Hi, not England but close... Canada Italian-barber. Has best prices for razors and blades. .

I recommend the Feather SS, I love mine, fairly forgiving for such a razor, and amazing shaves.
