Kodak DX4530 optional lenses

Has anyone here tried the optional lenses Kodak makes for the DX4530? I am considering the telephoto lens. Any comments on the quality? Kodak's telephoto for this camera only magnifies 2X, I would prefer more magnification. Are there any other sources of optional lenses for this camera besides Kodak? The camera has 37mm threads and an optional lens adapter that must be used when attaching other lenses or filters. I assume I could use any 37mm filters, but are there other brands of telephoto, wide angle, and closeup lenses that I could use?

If it would be appropriate to ask here, I would be interested in buying used accessory lenses for this camera if anyone here has them.

Thanks.
