I've reached some sort of compromise I think. Below are typical prices for the different sizes, built from semi-expensive woods and parts and with a hand rubbed shellac finish. All ukes have the characteristic Argapa sound, "one size löuder".
Piccolo, of cherry - 3500 SEK
Soprano, cherry or mahogany - 4200 SEK
Concert and tenor - 5000 SEK
Resonators, soprano scale - these are built in small numbers and individually priced.
The koa sets I have, all soprano size, I've bought from abroad. This will increase the price a bit. Also, fretboards of ebony are more expensive for me to get than those of rosewood. But in the end it'll all be a bit jumbled.
These are just rough figures. Depending on what happens prices can go up or down.
