For years, mainly due to lack of funds, I struggled with underpowered amps, cabs and combos, where I was always struggling to be heard above the sound of the drums. So my advice is, if possible, go for something that is louder than you think you require, as it's better to have power in reserve if you need it. Now I have the cash available to buy whatever I need, I've gone for a Markbass CMD 102P combo, which gives me both power and lightness. But I'd also recommend the new Fender Rumble V3 combos. The Rumble 500 has a 500 watt amp with a 2x10 cab and allows you to add another cab if you really need the extra volume (which you probably won't). They're reasonably priced new and are even cheaper used (well under your limit) and really light.
