There are very few new GPSes that don't support
NEMA. Chances are, if it is fewer than two years old,
it has NEMA support. Why not ask the person selling
the unit if it supports NEMA? If the seller would lie
to you about that, you shouldn't be buying anyway.

I like the Garmin eTrex (
http://www.garmin.com/products/etrex/).
It can be had for under $100. There are some less
expensive ($50 to $80) models but they have no
display at all. In a tracker, you really don't need
any display but I find it most useful for diagnostics.
I assume you are talking about a mobile 'tracker'
application. If you're stationary, you don't need any
sort of GPS.
Another thing to keep in mind... The GPS's antenna
must be able to see the sky. Many of the ultra-cheap
models have a built-in antenna. If you want to mount
the GPS and radio in the trunk of a car, for example,
you may need to find a more expensive model with an
external GPS antenna connector.
Take a look at the Garmin web site (above). My
father and I both have eTrex Legends and couldn't be
more happy with the product. A couple folks at work
also have Garmins with no complaints.
