We leave "SOLD" items on our website for machines that we often repair and provide parts for. This is to give you an idea of the products we typically carry, and direct you to alternatives you may not know about - we often have substitutes for out-of-stock parts, and are happy to recommend workarounds and different solutions to common problems.

Re: International Shipping: We ship internationally often and have yet to encounter a problem or complaint. We are very careful to test the equipment before itís packed and then to double box the machine with added protection when needed for front panels, etc. We are not amateurs or an ebay store; we know these machines very well and know what it takes to get them to you safely. We use USPS priority internationally which seems to be the cheapest. If you prefer another carrier (you should know who delivers to your area reliably) please let us know. Also please be aware of any tariffs that you may be responsible for upon pick up on your end. International shipping may be expensive but we will make sure it is not a headache on top of the cost. PLEASE NOTE THAT SHIPPING INTERNATIONALLY WILL BE A MINIMUM OF $16 EVEN FOR SMALL PARTS.
