the entry level scopes from hp and tek are now rigol and atten; chinese brands. rigol is ok but its NOT hp or tek!!
the last 'very repairable' scope from tek was the 2465 series and I'm seeing a rebirth of interest in the old analog scopes. check out all the chatter over at eevblog and you'll see what I mean. a few parts were having problems (20 yrs later) and after you replace some leaking electrolytics (just a few, not all) and replace a battery backed nvram chip (that holds calibration settings!) you are good for another 20-30 yrs. the battery in my Dallas nvram module is 20 yrs old and only supposed to last 10. I backed it up to a file, installed a new version, restored data from file and now I have another 10-20 yrs on that new battery/nvram module.
I am VERY sure that the rigol scopes won't last even 5 yrs in a heavy use environment. the company won't have spare parts, they are all specialized and it will cost a fortune to mail back to china, if you could even GET it fixed, 5 yrs after model was intro'd.
the smart money is on buying older used gear that has a huge community of owners and techs and who know how to keep the older gear running. for tek, there's a yahoo group that has some older tek employees monitoring it and offering help for those who are reconditioning their gear. you will NOT find that from the throw-away chinese brands and models.
smart money - for us hobbiests who can't depreciate gear in a few years time - is to buy older used gear.
