I did it - I went ahead and purchased the 5060 online. Now I just need to research the housing I want. I'm leaning towards Ikelite, but I need to do some more homework to see if the extra $300 over the PT-020 is worth it.
If anyone's interested - I found the 5060 online NEW, not refurbished at UBdigital.com for 404.99 (434.00 after ground shipping). I'm a little weary since it was so low and I've never bought from them, but the site had decent reviews. And it's not the international model- it still comes with battery, charger, etc. So hopefully I won't have any problems and I just lucked out. They're having this sale until the end of June.
So thanks everyone, I'm sure I'll be happy. And opinions on the different housings are always welcomed!
