I have a Digitech RDS-4000 time machine. It's a rack mount delay unit that is capable of all kinds of crazy delays and echos. Also has a sampling mode, has been modded to do delays a little longer than standard by simply turning the knob a little past its max setting. Pretty sweet. $100 shipped (it's big)
Alesis Philtre desktop filter effect unit and the hard to find power supply that is the only freaking power it takes. Pretty nice and compact filter capable of everything you'd expect but also has a unique and rad pattern mode. $80 shipped.
Thanks for looking.
