The Garmin 76 CSX is a reliable unit in the $250 range. Check the sponsor link through Tiger GPS for their prices.

You can get topo map support for the Garmin.

Another unit that I like better than Colorado is the Oregon. However, more $$$$

For a fully self-contained with high quality topos, my favorite is the Lowrance Baja 540. It is pricey and hard mount.

Overall, the Garmin 76 is portable and you can add topo support for a reasonable price.
