Erwin,
I calculated the total price at $90.657USD, without shipping.
Rufe conversion calculates as $32.95+-USD, from MDC website.
Tamiya A6M2 can be $110.00USD
To me, it is not a bad price. You are getting the conversion for free. But what is shipping to Belguim? That may put the price over the edge.
If you buy each item separately they may cost more.
I have a Swallow A6M2 and a resin cockpit and Rufe resin conversion I picked up years ago made by Pascal Huguet.

I'm happy with the quality of the Swallow kit. Some may not be. The Swallow kit is not a competition piece. Tamiya's kit is a competition piece. The Swallow kit doesn't have the niceties of the Tamiya kit. All flaps, etc. are molded in. It would take surgery and scratching to relocate them. The engine doesn't compare. The surface is scribed and riveted, though, and is really rather good. I don't recall if the cockpit glazing is 1 piece or 3. It's probably a 1 piece. It is by far less expensive than Tamiya's kit. Pascals cockpit compares with Tamiya's. I don't recall if Pascal offered a Beaching Dolly.
Do you want to make a non-competition Rufe or a competition Rufe?
If you buy it, and don't like it, I'm sure someone would buy it from you.
I hope this helps.
Sincerely,
Mark
