I would recomend the Picasso iv although I don't have one. I have a Retina BLT Z3 which I use on my A2500. (It can use both Z3 and Z2) Nothing has been written for it in the past 10 nyears while Picasso does. It is complicated to set up, and seems to be the source of annoying crashes. It doesn't do all that it was advertised, and if it does, well it wasn't explained in the manuals. I chose it because it allows you to use two monitors which I thought would be helpful in troubled times. (which it is) I.e., if something happens to the card, the 1084s monitor is hooked up to the Amiga port and not the card so you can problem solve. This happens a lot so this is useful but I think the card itself is the cause of this. When I originally got it, the only picasso was II and I thought that was to complicated. How wrong I was. Remember, one of the Amiga's advantages was to show more than 1 screen resolution at a time, i.e. a split screen with different res. which is very helpful, i.e., in Vidi you can have the upper screen of the picture your capturing in a higher resolution than the lower screen with the toolbox on it so that the buttons are a decent size. On ALL the graphics boards this is lost so if you set the graphics screen to a decent res then the button screen is so small you can barely see it. The Retina allows you to return to the Amiga graphics so you can continue to use this. For all the trouble I've had with it, this was a small item
