My condolences, along with the others'.  I'd recommend looking for a 
used Tektronix; my 7904 died (but not from zapping) and I found a very 
nice little 2465 on eBay for around $200.  Not quite as versatile but 
the price was right.

I've used a 10:1 probe for an "antenna" on numerous occasions & haven't 
had a problem.  But I take care not to get it too close to the 
secondary, for sure!
