I was considering it a while ago but was discouraged by the comments posted in this thread: http://www.audiokarma.org/forums/showthread.php?t=348114 . I´ve been using a Nikko EQ-1 for RIAA equalization correction according to adjustment carts posted on the net with good results. That was the best option available to me since I had already that equalizer which I had no use for. Meanwhile, I save money for a Graham Slee phono preamp (about 1 K $): http://www.custom-cable.co.uk/graham-slee-revelation-phono-stage-riaa-78rpm.html. A cheaper option mentioned in the above thread is the Elliot Sound Products project: http://sound.westhost.com/project91.htm . People also suggested another cheaper option: http://www.tdl-tech.com/data415.htm or http://www.tdl-tech.com/ppage2.htm but again it seems that a bit of DIY work is needed.
PS: If I had 2 k Euros available for this, I´d go for http://www.vadlyd.dk/English/RIAA_and_78_RPM_preamp.html .

If the 78 rpm records are from the late 40´s or early 50 ´s, the differences with the RIAA equalization are minor and you could listen to the records using a standard phono preamp (RIAA equalized) and your tone controls for minor corrections. BTW, if you are DIY skilled, you could consider the ESP project at a moderate cost.

Here there is the link to the equalization corrections needed to playback 78 rpm using a standard phono preamp and a equalizer (Appendix B):
http://users.hal-pc.org/~clement/Restoring Old Recordings.htm#Appendix_B
If you find a cheap good enough equalizer this would be the easiest and cheapest way to play any 78 rpm record. You may need to adjust the equalizer settings before playback by using the table provided in the link.
As an example, consider the Victor 47-52 column: you'll see that the deviations form the RIAA curve involve corrections that are smaller than 1 dB in the bass spectrum and not larger than 1.73 dB in the higher portion of it.
Onthe other hand, in the Decca 78 column you'll notice that larger corrections are needed (as large as 8 dB)

There are myriad different equalizations for 78rpm records (somewhere on the net is a table of 60 different ones), and many companies will happily charge you $800 for a $120 equalizer. The basic TEC TC-750 RIAA equalizer costs $43, and for another $25 (total: $68) the upgraded TEC TC-778 equalizer adds a second setting where there the high frequency boost is flat. It's a reasonable compromise for peanuts of money. My TEC TC-778 RIAA equalizer works great and the 78rpm equalizer works, but I don't actually have a 78rpm record nor a 78rpm cartridge so I haven't tried it on real records. I bought this device "just in case". I did not buy it for 24/7 audiophile usage, and for my application (affordable versatility) nothing in the market can TOUCH the price so I'm very happy with my purchase.
