Help finding 3.5 enclosure w/ big power supply (do I need one?)

Hello,
While researching enclosures I came accross one possibility that reviewers indicated had a weak power supply. The enclosure is a Macally G-S350SUA & specs indicate it has a 2A power supply. Maybe it's just poor quality, right?

The thing is, I checked into my hdd's power requirements, and "Spin-up Current (Max.)" is listed as 2.2A:

(1TB Samsung 7200 sata, model HD103SJ)

Even though that's max, I thought "I guess I'll be looking for an enclosure with a beefier power supply"...to be safe.
But I can't find any.
Suggestions? A "toaster" or docking station would be fine too - actually preferable, IF it's good quality.

much thanks in advance for any help!
