PIng))) with Picaxe 28X1

I am using a Ping))) with 28x1 proto board and have it wired per this article http://letsmakerobots.com/node/1276 i am using the code snippet from that article aswell. I am trying to determine the distance of my ping and am having a hard time debuging. How would i go about doing this?

Here is my debug code. 






 LET DIRSC = %00000000

 PULSIN 0, 1, what goes here for the input?

PICAXE Identification?

I have what I beleive is a PICAXE 28X1 chip, the #s on the chip are PIC16F886, 08103MD, is it a 28X1. I have done numerous things to get this thing working( http://www.sparkfun.com/commerce/product_info.php?products_id=8353 bought it from this site). Checked voltage all the way through the board, checked my COM drivers ( I have a serial cable, not usb), went through all of the PICAXE modes in the options of the Programming editor, made sure the COM1 was selected in the programming editor, 4.5 volts(3 AA).

Where to find a Picaxe servo upgrade kit in the US?

I've been trying to find a Picaxe Servo upgrade kit but the only stores I can find are in the UK and shipping is a pain, and not to mention the wait. Does anyone know of a store in the US that sell this kit? Or maybe just the 330k DIL resistor and an extra servo because I've looked and cant find anything the, resistor I need is 36 cents but shipping is 25$ and I can only find it in the UK.
