Whenever Arrow has a sale I always order from their UK site cause it's cheaper. And there's several movies with US releases on labels I don't collect as much, so I've gone with Arrow.
Also if you ever get into Chinese Martial Arts movies, 88 Films and Eureka have a ton of great movies. Plus Eureka's Masters of Cinema series and classic movies. Not to mention Indicator and Second Sight.
I got my region free off Amazon. Different seller but same model, and it works great.
I got an Amazon gift card from an award at work so I went with this one:
Works great and I love it.
Looks like you can get the series on blu-ray with original music for around $170 off ebay, and then you'd need to get a region-changable bluray player, which you can get for around $160 off amazon. So with tax, you're talking around $340 shipped for the original show with all original music in excellent blu-ray format. I get that that's insanely expensive for a 90's tv show, but I guess it depends how much enjoyment you're going to get out of it, and how much $340 means to you.

Of course if you're already in the UK, you're golden!

I've been using this one for a few weeks now and I really like it. It's a quick switch between regions and easy to navigate. Recommended.
