For 3.5 stuff, I'm going to approve everything in the magic item compendium.  Everything else 3.5 is a case-by-case basis, run it by me and I'll see (though I probably won't say no to a whole lot).<br/><br/>Also, druids and witches both get decent spells per day and can cast cure spells, so while they're not as awesome healbots as clerics, they can still do the job.
