Electronic/Machine Foot/Ankle/Calves Massagers

This isn't so much money-saving as money-splurging, but I've been frugal for ages and feel much in need of something to massage my feet more regularly than my DH is willing, or to bother having to go to a salon (so long-term saving on salon visits if we invest in the right machine - hurrah, I am money-saving after all! Not that I go to salons, but anyway!)!
I am also pregnant, and my feet and ankles could really do with some regular relief, so I think I need a machine!

So, am looking at an electronic foot massager, but there are a fair few to choose from, varying quite widely in price, and I am struggling to find a storeroom where I can actually physically TRY before I buy, so any recommendations would be appreciated, both for the actual product, or better still, a store (ideally in London) where I could try a few of the machines out, and then decide.

Have so far found:
- SANYO Foot Massager HER-FA500 with heat therapy and shiatsu, £480 (http://www.amazon.co.uk/SANYO-Massager-HER-FA500-therapy-shiatsu/dp/B001BL705U/ref=pd_cp_d_2)

- uComfoot Warm Leg Massager (Upgraded iComFoot) - Massage Thighs, Knees, Calves, Ankles and Feet with Sole Shiatsu and Infrared Heat Therapy £530 (http://www.amazon.co.uk/uComfoot-Warm-Massager-Upgraded-iComFoot/dp/B0037RUB9S/ref=sr_1_28?ie=UTF8&s=drugstore&qid=1283519684&sr=1-28)

- TK528 FOOT Massager £385 (http://www.amazon.co.uk/HBR-Health-Beauty-Relaxation-TK528/dp/B002J992OK/ref=pd_sim_sbs_d_3)

and

- Foot Ankle Calves Calf Leg Legs Massager, £200 (http://cgi.ebay.co.uk/New-Foot-Ankle-Calves-Calf-Leg-Legs-Massager-UK-MODEL_W0QQitemZ350390110845QQcategoryZ36451QQcmdZViewItemQQ_trksidZp4340.m444QQ_trkparmsZalgo%3DCRX%26its%3DC%252BS%26itu%3DSI%252BUA%252BLM%252BLA%26otn%3D20%26ps%3D63%26clkid%3D5945485968983351048)

So, quite a price difference, if the £500+ one is mega awesome, I'd seriously be tempted, but not sure how much more mega awesome it is compared to the £200 one?

Thanks in advance.
