Harley Benton HB-20B

I would say that this is a valid option if bought as part of bass-bundle or something like that. Price is low, but so as the sound quality coming out of the speaker. It's usable as a bedroom amp, but the size of it, and especially the depth is not that great (which is expected for this speaker size and cabinet).
Aux input and speaker out I find most usable, as the sound there is decent, and it's great for practice. Overall considering the price, this is a usable peace of equipment for practicing through headphones, and if you want to let some sound out just for fun, but don't expect much more from it (if on a budget or in doubt if you will stick to the instrument, this is a decent buy...was my case...otherwise look for something with a bigger speaker and more expensive, I think it will make a significant difference in usability and overall experience).

Pros:
- Lightweight, AUX in, Headphones OUT, decent build quality

Cons:
- Small speaker, lacking depth, speaker not great tone, and burping on higher volume
