Playing mono records properly without breaking the bank - a phono pre-amp question.

Hi there.. I can use some suggestions for playing mono records properly.I'm about to put together my vinyl system and trying to figure out how to best play mono records without having to either buy a separate TT, have a turntable with two tone arms or have a switchable head-shell, all of which are not an option at the moment.  Someday, I think having two tone arms will be the way, but now I need the most economical way to have a nice experience.
I will have at a minimum, a nice stereo stylus/cartridge, but I'm wondering if I should be focusing my phono-preamp search to those with a dedicated mono switch?  I have a Hegel integrated and there's no mono option. 
Are there  simple ways (contraptions)  other than a phono-preamp with a mono switch, to achieve high quality mono playback with a stereo stylus? My search for the right phono preamp would be much easier if I knew I didn't need to make sure it had mono.

Appreciate any suggestion or direction - would love to hear your person experience playing mono on a generally "stereo" rig.
