10-meter-only radios are not very common. Most of them are based on CB radios and they may not have useful features that an all-band HF radio would have. You may only have 10 meter privileges now, but an all-band HF radio will fall right into place when you upgrade.
Pretty much any HF radio can be used with sound card data modes such as FT8. There are several sound card interfaces on the market, such as the SignaLink USB, that can interface between your radio and your computer.
Newer HF radios often have built-in sound cards. You don't have to buy an interface as all it takes is a USB cable between radio and computer to get you going with sound card data modes.
Looking at the new base station HF radios on DX Engineering's website, here's what you'll find:
Icom IC-718, no built-in sound card interface, $860
Yaesu FT-710 Field, built-in sound card interface, $875
Yaesu FT-710 AESS, built-in sound card interface, $945
Icom IC-7300, built-in sound card interface, $1100
Icom IC-7100, built-in sound card interface, $1200
Yaesu FT-991A, built-in sound card interface, $1200
