Toilet Flange question

I am installing a new toilet and 3" pvc drain. Please tell me if this is ok:

1. Instead of closet bend, I used a 90 deg el. Ok?
2. There isn't enough vertical room to install a stub of pipe to get from the el to the flange so I got an inside-mount toilet flange that fits directly to the el. Is it ok to use this?

The plumbing supply place didn't sell inside-mount flanges bkz they said that no good plumber would use one. But I've found them to be readily available elsewhere (HD, L's, online). If they were really that obsolete, I would have thought they'd be harder to find (kind of like vent tees


Any help appreciated.

If thats all you can do go for it. It should work.

They are not "obsolete" it is just that no plumber would use one, since it could be a continual service problem that he would have to take care of for free.
