Recommend 10 meter only, or nearly only, transceivers please.?

I'm thinking about buying a used 10 meter transceiver and would like advice regarding which rigs to avoid and which rigs to look for. I'm particularly interesed in rigs that are capable of CW transmission. If they have CW reception filters, so much the better. Of course, if they have capabilites on other bands, thats acceptable. I'm asking for info on 10 meter only rigs because I ume rigs with restricted capabilities will be less expensive. 73
