How much does thrusters cost?

I'm curious to know, can you provide me with an estimate on the cost of thrusters? I understand that the price can vary depending on factors such as the type, size, and intended use of the thrusters. However, I'm looking for a general idea of the cost range to help me better understand the financial investment required for such equipment. Is there a typical price range that these thrusters tend to fall within, or do they vary greatly in price?
