I have a Soloette and a Yamaha SLG200NW. I find playing the Soloette much more similar to playing a standard classical guitar than playing the Yamaha.
Why have 2 silent guitars? I bought the Yamaha for my Dad to use playing standing up with a strap at gigs, which it is very good for.
You can sometimes find used Soloettes online at e - b a y or Reverb for about half the cost of a new Soloette.
I bought my Soloette new in 1998 and have replaced the frets twice, the second time with stainless steel frets. So, yeah it gets a lot of use. It is great for practicing at home when other family members are in close proximity.
