Grandpa Tom: Welcome to the SZ! Both the PSR3000 & Tyros are terrific boards. I've owned the PSR2000 (predessor to the 3000, played the 3000, and have owned & played the Tyro for over 2 years now. Here are some IMPORTANT things to consider, especially for those perhaps visually challenged. The Tyros' includes a much larger, BRIGHTER, and fully ajustable color LCD tilt screen, and includes much larger (easier to read) text (fonts) than the PSR3000.

The Tyros also includes larger (and some of them even light up green or orange to signify operation status) arranger navigation & LCD screen select buttons making for easier selection, especially critical when peforming on the fly.

If remote footpedal control is important ot you, keep in mind that the Tyros includes 3 footpedal controller ouputs vs 2 on the PSR2000.

If you've played church organ previously, then I think you'll find the Tyros key feel more similar to that organ than the PSR3000. As far as 61 vs 76 keys, if you plan to play mostly in arranger mode, then 61 keys will be quite adequate as left hand 'full chord' triggering takes no more than 1-1/2 octaves, leaving 3-1/2 octaves for right hand melody & fills, only a 1/2 octave less than available from middle C to to the top note of a full 88 note keyboard. If you plan to do a lot of solo keyboard playing (arranger function OFF) then I recommend a 76 (or better yet 88) note keyboard instead, or simply connecting a 76 (or 88) note keyboard controller to the Tyros or PSR3000 via midi.

Grandpa Tom, looking forward to hearing which keyboard you end up deciding on. I assure you neither will be a bad decision, but one of these just more ideally suited for your individual needs.
