This one is tricky as the answer entirely depends on your skill level (and, obviously, budget). The price of a potentially decent interface generally starts at around 400 USD, 600 USD being the upper threshold of what can be referred to as entry-level equipment. Models that fall within this range often produce reasonably good sound. The main problem to avoid in a cheap audio interface is latency, which the reviews by ordinary users and experts alike tend to highlight, especially when they focus on drums. Thus itu2019s always a wise approach to gather first-hand information before you actually invest in any device of the kind.
