DLP-PROP vs. PropSTICK USB

Hi all,
I was looking at the DLP-PROP that is offered in the third party·propeller tools link (http://www.parallax.com/propeller/tools.asp).
The DLP-PROP is $69.95 and the Propstick is $79.95.
The DLP-PROP has·a 6MHz crystal vs. the 5MHz in the·PropSTICK.
Other than that, is there a significant difference between the two that·I have missed?
Any opinons on the DLP-PROP?

Thanks,
Joe

    Off the top of my head, I'd pick the PropSTICK USB simply because it's Parallax and I know their stuff is good quality.

    If you really care about the $10, I'm sure the DLP one is fine too.

    One difference that I see from the documentation (I don't own either one of them) is that Parallax's PropStick USB is pin compatible with the Propeller, where as the DLP-prop pinout is not the same.

    It's a small detail, but I myself would prefer a module that's pin compatible with the chip that it's meant to replace.

    The DLP-Prop doesn't actually have a crystal, it derives its clock from the FT232R chip on the module. If it's not plugged into your USB port, it won't work.

    Hey,
    Thanks everyone for the input.
    Sounds like the Propstick is the way to go.
    Which was my first inclination because of the quality that Bergamot brings up.
    I have always had good experiences with Parallax, clear back to when I got my first bs2 many moons ago.
    I hesitated in getting the Propstick because I am ordering other components not available at Parallax from the same company that offers the DLP-Prop.
    So to save some shipping costs, I pondered just using DLP-Prop instead of the Propstick.
    But it sounds like the DLP-Prop (which may be a fine product) is just not what I had in mind.

    Cheers,
    Joe

    >>The Propstick is not exactly pin-compatible, but the differences are minor.

    It's pretty darn close - I'm currently running a PropStick USB in a Propeller Robot Controller board (designed for the 40 pin Propeller chip) and the only changes I needed to make were to not populate the crystal and the EEPROM on the PRC board.
