recommendations for cheap diesel compression tester?

[Adam32]

I am in the market for a diesel compression tester, but most of the places that sell them don't list the full dimensions of the glow plug adaptors (other than thread pitch) that come in the kit. I have only seen a few dimensions listed on the more expensive kits and I want to buy something as cheap as possible! I don't even need anything with numerous adaptors (apart from straight and right angle connector), as I have just one vehicle I work on. As long as I can be 100% sure it will fit my engine I will buy it.

Below is a picture of one of my spare glow plugs (Bosch Duraterm 0250201055 M12x1.25) with a measure next to it. Can anyone recommend a cheap kit that will definitely match up to my plug?

Most of the cheap testers on eBay for around £30 will have the 12.125 thread adapter, it's one of the most commonly ones used..

yes but they don't give you the length of the adaptor or other measurements. If too long it is no good. Some of the more expensive kits do give you measurement, but on the cheaper kits there is a complete lack of information.
