I've got a non-Pilot GPS-3, cost about £120 or so (with UK roadmap). Would be nice to have the HSI-like screen of the 3-Pilot, but in general i'm very happy with it. Personally I prefer a moving map over the most simple GPS displays - arrive at waypoint VFR-style, glance at GPS on kneeboard to confirm, that's it. I'm not using it to dodge airspace or anything else so I don't care that the map is non-aviation.
