Well that's true and it isn't. If you're lucky, you can still find a good old sneaky-pete for sale. I worked as a pool table installer/restorer/mechanic for a few years, and the guy I worked for had a few Dufferin sneakies (Dufferin then, not dufferin now) in his armament. Needless to say I acquired one post haste. I believe the deal we worked out was $75, and I bought the last 21oz he had.
It plays as good as anything I've ever used, I prefer it to a lot of this high-tech crap guys have nowadays. Any player will know it from the 1.5 inch ferrule and the pro-taper, but that isn't the point. I love how a one-piece wood cue hits, and this is the closest thing you can get to a portable version of that. (IMO)
I break with a simple cuetec 19oz black on white with the glass over wood shaft, not the SST, whatever they were pushing right before that. I don't care for the glass, and I've scuffed most of it off with a scouring pad. A lot of guys will turn their noses up at my cue-case, which holds less than $200 worth of stick. I've even had guys tell me I should break with the pete and play with the cuetec, idiots.
With these two cues you should be able to do just about anything for under two bills. Simple, easy, reliable. And in that sense, the sneaky-pete does still exist. People are too busy noticing what you don't pull out of your case.
And if you are lucky enough to find a Dufferin like mine, keep an eye on it. I had to go table to table one night looking for that long ferrule, and finally found it in the hands of some unwitting player on table 22.
As for playing with Budweiser or coca-cola cues, I wouldn't recommend it. I bought one off of eBay once and it was warped out of the box. The shaft wasn't even rock-hard maple, the grain was loose and it was probably teak, like the Asian knock-offs often are.
