Wanting to add oil pressure in HPT, which sending unit to use?

I've noticed at WOT my factory oil pressure gauge is doing some goofy stuff, dropping pressure, erratic readings.

I am wanting to add an aftermarket oil pressure sending unit and monitor it it in HPT.

Obviously I need a 0-5v sending unit. Is there any particular one that works better that has good data?

Thanks for any info.
