Can someone recommend a relatively low pressure boost gauge to me in 2 1/16" size?

My car is a US 2.5RS w/turbo kit and it only runs 5 psi of boost currently. I'd consider running as high as 10psi some day but never much more with stock 9.7:1 compression. A 0-30psi or even 0-20 gives me a pretty small sweep of the gauge. Years ago, I had a VDO gauge that read 0-15psi but haven't found like it in my recent searches.

Thanks!
