I'm still excited waiting for my Wanderlust too - it seems like forever. I've had my old 90mm lens CLAed, just for it. I bought a used Super wide field Caltar (on Ebay) to replace old 90mm and use on my Wista. Weight and size is not an issue for the Wista. I've also bought a two way level and one of those plastic viewers from the guy in Israel. I purchased two range finders also, one Russian Blink and a Japanese Walz. The Bllick is much lighter and stylish, but the Walz has a large focusing dial and a longer range before reaching infinity. Also the Blick has a light rose viewer and the Walz has a light yellow viewer color. I don't know if those tints are to match a filter color or just the result of aging. After trying them out on my Wanderlust I'll keep one and sell the other.
I also bought another ten film holders, but worst of all as you may have found out on your own, once you get on ebay it's had not to buy things you don't really need. Waiting for my Wanderlust ( I don't do waiting very well) I decided I needed a small rangefinder 35mmm camera so now I have a Voitlander Vitoret DR, a Cannonet Ql19 and a Yashica Electro GSN. I didn't really need them and I'm in trouble with my wife. Sure hope my Wanderlust comes soon; so does my wife.
Well, Happy Trails,
