Do you have an imaging camera already? Is it OSC or mono, filter wheel? once you start adding things down the camera end all the weight starts adding up and is often causes focus slip or tilt or the stock focuser can't even hold the weight, a lot of people upgrade their focusers.
I am not familiar with the 1100's focuser, however aftermarket focusers such as moonlite or feather touch are considered strong.

I think people would consider the lodestar guide camera
http://www.sxccd.com/lodestar-autoguider sensitive and more recently the qhy5 II
http://www.gamaelectronics.com.au/guiders.html and ZWO 120mm
http://www.opticscentral.com.au/zwo-...l#.VonnQkq4ZaQ These will help you obtain faint stars to guide on (they are going to be generally very faint at 2800FL).
its worth trying to consider what your imaging camera will be - if it needs a filter wheel or not, if it needs any correctors, spacers. If you haven't chosen an imaging camera and are thinking OSC the stock focuser maybe ok with an OAG but it would be worth asking someone else who has one - or try it and see how it goes, perhaps upgrade the focuser later.
