For the lucky ones that live in Paid Android Markets, you have access to way more apps... both free and paid. For us here in the Philippines, we have some free market apps, and no paid ones. Although inserting a foreign SIM card and accessing the Marketplace via WiFi works, it's a bit cumbersome to keep switching SIMs.
Market Enabler does a great job of 'faking' ones location and giving access to the Marketplace of the region/country it's faking. Albeit you still can't buy paid apps without a credit card issued from an approved country (BOO!!!!) you do get more free apps, and even some Google app updates (Like the new Streetview on Maps and Translate)
Give it a try. Worked for me! :)
