You may want to wait and see what the new Rupes machines will be like and sell for. I have a DeWalt rotary - the old battle tested one not that new plastic POS, a Cyclo that I got from Todd Helme - traded my Flex, and a PC and PCXP. I wish I had tons of cash and could get one of each like George but times are tight and I have learned to work with what I have. I am a part-time detailer and 90-95% of the time I just use the PCXP with MF pads and M101-105-D300. OMG...like isn't that machine supposed to be crap?! and you can't correct with something that old and weak, uh huh, right, move along keyboard detailer. Now, I'm sure there are better, faster, and nicer machines available. But, ask yourself this, how many cars do you do that actually require full correction? If you're just starting out and have polished a few cars and you see the difference, congrats, but, Joe Public just wants a clean shiney car and some wax. I have worked my butt off on daily drivers and I'm sure I impressed their owners with my attention to detail, but, most of the time it was overkill and they just wanted - you get it....
If you do this for a living you probably don't read my posts anyway, so, weekend warriors and part timers, read on - first, listen and understand what the guy wants, is willing to pay for and then explain the pro's and con's of paint correction. I'll bet, they just want a wash and wax, and oh yeah, can you get that coffee stain out too? Now, your little detailing heart is crushed, afterall - you can polish paint, you KNOW it will look better, you KNOW if it was yours what you would do. Been there, done that, it took a while but I got over it. Now, it's just a job, it's x number of hours times x dollars = more $ for the family. I could give a rat's arse if it had swirls out the ying-yang, if the customer doesn't care, I don't either.
Now, enough doom/gloom, enter the guy that DOES know and appreciate a detail, and can tell a swirl from rids and wants (spell that - pays) for correction. Those are the ones that make it worth doing. But, don't knock the volumn work, it pays the bills!
Now that I've got that off my chest and I hope maybe it will help a few new guys avoid mistakes I made. The Rupes vs Flex, like I said, I traded my Flex and altough I haven't used the cyclo that much, it's only because I haven't found MF pads for it, and it does a decent job with Orange pads. I just didn't like the Flex, it was loud and if I'm going to use forced rotation I'll use the DeWalt, at least it's quiet and spins the right way.
