In the biggest resorts - Bansko, Borovets and Pamporovo lifts are okay but don't expect them to be as big as the ones in Austria (the resort itself). In the smaller resorts - they usually have one lift which is not a good quality (sloooow) but the price is very low and it attracts a different kind of people - social riding, also worth doing it :) During the weekend expect queues everywhere. Weekdays are okay.
