I'm not gonna get into Lavalier mics for now - simply can't afford them (unless I find some worthy cheap deals to experiment with). But when I do, (if I'll really need to get Lavs for some wide-shot dialogues) I'm thinking to have a cheap setup like this http://www.danmccomb.com/posts/678/zoom-h1-as-wireless-lav-4x-cheaper/ with Tram TR-50 plugged directly into Zoom H1 (yes, you can't monitor, but hey it's a cheap solution). From one of the comments on that post, someone mentioned Oscar Sound Tech OST 802 lavs, which seems to be 1/3 of the price of TR50 (circa $120).

Here's a comparison/test with Sennheiser ME2

Have you ever heard of these OST802 lavs??? Someone even did a comparison between Tram TR50 and OST802 here http://proaudiocoalition.com/index.php/cdolan-pac/story/my_lav_mic_has_a_first_name_its_o-s-c-a-r/ (Tram TR-50 in the right ear, and OST802 in the left ear). OST802 indeed sounds very very similar to TR50 (although OST802 sounded a tiny bit "flatter", but nevertheless a whole lot more pleasant than Sanken COS11D or Sennheiser ME2).

What's your opinion?
