I currently own a PSR-E433 that I got new in 2013. I've considered buying one of its several successors, but just don't think the additional features they've added were really that important based on my particular needs. And additionally, in my opinion and also in the opinion of others on this forum, the key feel of the E433 is noticeably superior to any of its successors. So, I've just kept using my E433 all these years.
Normally, I have had my keyboards, including the E433, set up in a structure that I built that resembles a home organ -- including having a set of bass pedals. But in case I start gigging, and to practice songs in what would be a gigging set-up, I made a portable stand that supports two keyboards, so I have moved the E433 (and my Roland Gaia SH-01) to that stand and have been practicing arrangements of songs using that stand -- with the big difference being that this "gigging stand" does not accommodate bass pedals, so that I had to work out other ways to add bass to my playing.
So, this is fine as far as it goes, but now, my organ-style stand has just been sitting there, half empty. And since I have not been playing on the organ-type stand, I'm concerned that my bass pedal playing will get rusty.
So, I have been looking for a back-up for the E433. I could get a different keyboard (Yamaha or otherwise) for the organ-style stand, but I figure it is best to have something with at least similar features and a similar layout as the E433 -- like having the registration buttons in a similar location -- so I can keep a similar playing technique. And if I get another E433, then I could easily exchange data between my main keyboard and the back-up. This would also make it a good back-up in the event that I do start gigging and if my main keyboard stopped working right before a gig.
However, what I've noticed is that E433's are surprisingly difficult to find, and what is out there is often very expensive. I've been looking at eBay, CraigsList, and Reverb, and of the few E433's I see, most are $300-400 when shipping is included. To me, that's quite a bit to spend for a ten year old keyboard that was $250 when it was new. It ain't a CS80 or a Mini-Moog! And if anyone checks Reverb and sees the $250 E433 in Miami, Florida, please note that it was being sold by a music store, and when I went to my local branch of that store, they said I could buy it there and they would ship it, but when I tried to do so, they found it had already been sold. I have no idea why they are still listing it.
Well, I finally saw one on eBay for a reasonable price -- $170 with shipping costs of about $33. It was described as fully functional, and the seller has a 100% positive feedback score, so I figured I'd grab it! It will probably be here within about a week, so I'll keep you posted!
