I've been looking around to see if there's a relatively cheap (around £5) accelerometer / tilt sensor in a DIP package for prototyping. Breakout boards exist for the ADXL335 but seem to be comparatively expensive.
Does such a device exist?

Well I presume you want a DIP for rapid prototyping needs and you can't work with SMDs,
So check out sparkfun's tutorial they have a very comprehensive list!

The cheapest one I could find is this : http://www.sparkfun.com/products/10955
I'm not sure if you want a tilt sensor or an accelerometer, if you just need to differentiate between two discrete positions, you might do well with a mercury/ball tilt sensor : http://www.adafruit.com/products/173
Pros:Cheap and easy to use/interface.
Cons: its a binary output, acts like a switch.
I took a look at Sparkfun and Adafruit like Shungun, but SeeedStudio have a few more. Their cheapest is a breakout for the ADXL335.
If you don't mind and are able, you could potentially use/find a surface mount accelerometer like the MMA1270EGR2 and solder to a breakout board like this one from Sparkfun or one from Scmartboard.
That method doesn't end up being much cheaper, but you might find you'll have a bit more flexibility choosing an accelerometer.
Consider these http://www.parallax.com/Portals/0/Downloads/docs/prod/sens/28526-MMA7455-3axisAccel-v1.1.pdf $20 from Digikey (1x) I2C bus suitable for UAV stabilization or embedded solution. If you want analog out... those are avail too.
