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.

Just use a good stereo cartridge with good channel separation. 

Lots of garbage being spewed out trying to sound knowledgeable or scientific. 

You dont need to disable the stereo cart. The ever-so-slight differences in channels will be cancelled or helps to add depth to the playback. Disabling causes a very lifeless, dead, flat quality to playback. Save yourself the trouble and expense.
I might disagree here.  Going mono does a lot to cancel out scratches and pops.
Setting aside whether or not there is a technical advantage to a true mono cartridge over a stereo one the real point here is that if you are going to the trouble of creating a second dedicated mono setup then this is a real chance to choose the flavour of cartridge that best fits with mono recordings. Maybe you prefer the sound of 50s mono played back through a cutting edge MC -- if so great. But for me listening to the Chordettes through my Zero despite it's ridiculous tracking force (3.5g) and far from svelte body has a magic, a fullness, tone and amazing sense of depth that somehow is missing on my far more expensive stereo rig.

And yes the same recording owned in both mono and stereo mixes is often preferable in the mono. Generally 50s and early 60s cutting setups delivered better frequency range (more HF) in mono than stereo (per my conversations on this topic with Tim de Paravicini) so that may be part of the reason. Anyway there's so much to offer and find in mono -- a mono switch is absolutely a good place to start (and helpful for hum cancelling even if you get a mono cart -- that's another topic) but don't give up on the dedicated mono search too soon.
hrabieh, your 12/10 summary seems like a "sound" solution.  ;^)

Hope you then enjoy those mono treasures.  For the future, keep in mind the differences with older (pre mid-60s) mono releases.
