MVF, I'm an old dude that has been playing keyboards for 60 years having owned keyboards from Sears, Lowrey, Farfissa, Panther to a Hammond C-3 which I still own. Here's my recommendations, if you want an inexpensive keyboard, look for a used Casio 1630 or 3100. I think there's a Casio 3000 for sale on ebay for $279.00 dollars. As a musician, I purchased the Casio 1630 from BJ's Store for $300.00 dollars some 20 years ago and the 3100 about 10 years ago. There are enough rhythms and tones that will keep you busy for a long time. I just purchased a used Roland G70 last year and I've put 80 songs on cds since November of 2021. I purchased the Casios( as a hammond owner too embarrassed to let my friends and fellow musicians know I own Cassios} so I wouldn't disturb my family with the Hammond. I wish they had the technology that's in the Casio keyboard back in the 60's when I played in bands. I recorded at Capital Studios in 1965 and my Casio sounds 1000 time better than the Farfissa I played then. One last thing, both Casio keyboard I mentioned are 76 keys. The Korg E50 has 61 keys. I'm not sure if they make a 76 key model.
