I got my OM-1 for 280 DKR ($45, £25) with a f/1.8 50 mm lens. Great condition. But £38 is a great price, too.
I use 1.5 volt cells and the meter under-exposes by 1/3 stop. I set the ISO rating to 1/3 stop lower (e.g. ISO 400 is rated as ISO 320) and that fixes the wrong metering.
I use no converter or Zinc-Air cells as I am happy with the way I got my OM-1 working.
