When I registered MachosCalientes.es I had problems finding registrars that had English interfaces. You may have a similar problem registering domains, though since you live in Panama I doubt Spanish would be a problem with you. I tried EuroDNS but had problems with them (my credit card thought they weren't legit), by the time I got to the bottom of that problem I wasn't comfortable with how expensive they were, so I signed up to be my own registrar with Tucows, and can now register the following domains (as well as the standards)...

* .ASIA
* .AT
* .AU
* .BE
* .BZ
* .CA
* .CC
* .CH
* .CO
* .DE
* .DK
* .ES
* .EU
* .FR
* .IN
* .IT
* .LI
* .NL
* .TV
* .CO.UK
* .ME.UK
* .ORG.UK
* .US
* .WS

If you need to register any of those domains, let me know and I'll give you a URL to use. You won't need to pay the set up fee I had to pay, and since it's with Tucows it's all legit, above board and safe... It'll wind up being a lot cheaper than EuroDNS. All I ask is that you keep support questions to a minimum - the margins on registration aren't good and I don't really want to get into the business of it. Even though I can register things more cheaply by myself I still use Domain Shack for registering most of my domains - 'cause I value their support...

BTW, it's REALLY easy to to find good domain names in things other than .com...
