Bass Shaker Amplifier

Can anyone recommend a reliable but reasonably priced Amp to power either 2 AuraSound Ast 2b4 shakers or 4 dayton pucks.
Have seen some cheap lepy amps online but not sure if they are upto the task.
Please help with some suggestions.
Nice set when you need to connect 4 BShaher. It is a pity, on the other hand, that it can only deliver 4 x 50W, it could be more.
But still a nice design.
Thanks for the information.
Personally, I am looking for something that can deliver over 100W 4 ohms, which won't ruin my money pocket
