Both are from 2000 and have the same appearance, but considering their age, they are in good condition. 【3G】Although unmaintained, there are no problems with the appearance, video, audio, opening/closing, remote control operation, etc. 【B1】This model can record BS broadcasts, and the difference from 3G is that it has a decoder terminal on the back (no decoder included). This unit is also unmaintained, and there is a noticeable scratch on the upper rear, but like the 3G, there are no problems with video, playback operations, etc. (Slightly discounted due to the scratch). There is only one remote control, and it is currently set to 3G, but it can be switched. The TV operation section is compatible with current Panasonic products. If you want either one, please comment before bidding, and I will respond promptly. In that case, since there is only one remote control and one cleaning kit (as a set), please let me know which one you would like to include. 【3G】With remote control set: 5480 yen～, without: 4480 yen～. 【B1】With remote control set: 4980 yen～, without: 3980 yen～. If you want both, it will be 9480 yen～. Both units come with a power cord. The cleaning solution for the wet cleaner has evaporated, so only the container is included, but a DVD cleaner can be substituted. Neither unit has a box or instruction manual, but I will pack them carefully and securely when shipping. Shipping is set for 4-7 days, but this is to account for unforeseen circumstances, and I usually ship quickly.
