I'm not sure they would be of any use to anyone but I stumbled across these 50:1 gear motors for £5 each from the UK:
http://shop.pimoroni.com/products/micro ... armotor-mp
They say they are 50:1 but have a speed of 420rpm and a stall current of 700mA. I therefore believe that these are Pololu 50:1 MP motors for a very decent price.
I believe they are these motors:

There are also quite cheap (I think) wheels as well. Just check out this link for the full range:

I hope this has been useful!

Re: Cheap gear motors and Pololu wheels
I found these on ebay I have used the 30:1 motors in my new Defiant and though reasonably quick (830 rpm at 7V) seem quite controllable.

If you want more speed they do 20:1 (1230 rpm at 7V) and 20:1 HP (1500 rpm at 6V).
They do have a shallow grove across the shaft but it has no real effect for our use.
They come out at £4 each or £3 each if you buy 10 with £2.25 delivery and they are in this country with a fast delivery.

Re: Cheap gear motors and Pololu wheels
Good spot Pete. Are the HP ones actual HPs? If so that'd be awesome given the price.
Noticed that Hobbyking's also started selling gear motors for £2.50, including a 10:1 version, all which should be next day shipping, albeit at HK rates

Re: Cheap gear motors and Pololu wheels
I was looking to get some cheap gear motors and noticed that the hobbyking ones are now £4.10 plus postage but I found these on ebay.
http://www.ebay.co.uk/itm/DC3V-6V-12V-N ... 2749.l2649
I went for the 300rpm at 6v which a £2.46 and free postage seem good value.
I bought 10 and they took only 19 days to arrive from Hong Kong.
I just checked the speed in both directions on all ten and the highest was 296 and the lowest 285 which is very consistent.
They have a stall current of about 500 ma.

Re: Cheap gear motors and Pololu wheels
I was searching for plastic spur gears and found these gears with a D slot built into them. I thought they were interesting:
