That's a lot of money to not have real 'stomp box' functionality. One still has to step from one Fx to another. The first I found on the Thomann site with a button for each Fx is the Mooer Red Truck, slightly less expensive, and with 'real' stomp box layout and simplicity.
Far less expensive, and easy to use, is the Valeton Dapper Mini 4 Fx strip; this has the inconvenience of having to switch manually between Overdrive and Distortion. The Mooer GE100 and Valeton GP100 will both do what the Boss does, at less cost (the Valeton maybe a little tougher than the Mooer, if they're going to get mistreatment...).
Hope this helps; good luck with the project.
