I have a Big Sanyo M-9996K and a Small Red Sanyo MS-300K for sale because i dont need 2 of them. I can get on with just one specimen for my collection. What i am looking to get for the M-9996 is 135 euros plus shipping and for the MS-300 55 euros plus shipping. The M9996 is powering on and receives Radio Stations as it should but it will surely need a change of belts and the MS-300 misses the small knob for the tape counter and will need a change of belts too . Especially For the Sanyo MS-300K i can trade it for the same model in yellow or a blue colour. Here are some pics of them. Shipping cost for M-9996 will be around 60-65 euros and for MS-300 around 25-30 euros. Both of them will be around 70-75 euros.
I would go for them since the prices you are asking are very reasonable and to complete my mini/midi collection of sanyos but went on too many projects on the same time and lost track of finances!
