THE ROLAND SDE-1000 IS A VERY WELL BUILT DELAY. THIS ONE HAS MINIMAL RACK RASH. I'VE TESTED IT AND IT SOUNDS GREAT. IN PROGRAMING, ONE HAS THE FACILITY TO ENTER BY MILLISECONDS AND SAVE RESULTS. CURRENTLY MEMORY BACK UP IS RETAINING PROGRAMMING HOWEVER THAT COULD CHANGE, I'VE NEVER REPLACED THE BATTERY(A PREVIOUS OWNER MAY HAVE) I CAN'T GUARANTEE BATTERY'S TIME LEFT. COMES ONLY W / IT'S ATTACHED POWER CORD. I WILL PACK IT SAFELY. SHIPPING TO LOWER 48 ONLY. NO INTERNATIONAL SALES. PAY PAL ONLY. THANK YOU FOR LOOKING AT THE ROLAND !!!
