New to hobby. Where to buy hardware etc?

[lastlight]

Hello,

Like I said this is my first try at the marine game. I'm looking for good deals on some hardware and other things and wanted to know where the smart reefer shops in Calgary for various things.

What's a reasonable price for an ASM G1X Skimmer? I plan to get one and I'm currently hunting around. Do you people shop online or is it cheaper in the long run to buy locally?

RO/DI? I've found a couple sites that are highly spoken of...which units are a good buy locally?

Pumps. Anyone use Quiet Ones? Are they quiet and are they dependable? If not, which brands would you recommend?

Tunze Turbelles. Do people here use them and if so, did you have to buy them online? They seem like a valuable addition to a tank.

Finally, what's a good place to buy maintenance things like salt, test kits, meters etc?

Do people here generally shop in one place or all over town?

A lot of questions but hey, I'm curious =)

Cheers!

Brett
