Artificer Dilettante: numbers?

[WirelessJoe]

I've done a cursory forum and Google search, and can't find any specifics about what I'm looking for. Has anyone done the math or have any insight on the Helf Arti Dilettante and improved Dilettantes? As a refresher:

	
Half-Elf Dilettante: Artificer 	
Passive 	
You have watched the artificers of House Cannith work their trade. 
You gain proficiency with all crossbows, and Artificer Knowledge: 
Scrolls (You gain a +2 bonus to Use Magical Device checks when 
using scrolls, and their Caster Level is increased by one - this Caster 
Level increase is capped by your Intelligence modifier.) You are able 
to use wands and scrolls as if you are a level one artificers. For 
item use purposes you count as a level one artificer in addition to 
any other classes you possess (though this does not grant the 
ability to use Rune Arms). 	
Requirements: Half-Elf, 13 Intelligence 

Improved Artificer Dilettante I: Your knowledge of magical items 
has improved, and now extends to potions. Also increases your caster 
level in your dilettante class by 1, so you are now treated as a second 
level Artificer instead of first level for scrolls and purposes.
AP Cost: 1 	Level: 5 	Progression: 15 	Requires: Half-Elf Artificer Dilettante
	
Improved Artificer Dilettante II: Your knowledge of magical items 
has improved, and now extends to wands. Also increases your caster level 
in your dilettante class by 1, so you are now treated as a third level 
Artificer instead of first level for scrolls and purposes.
AP Cost: 2 	Level: 10 	Progression: 34 	Requires: Improved Artificer Dilettante I

Improved Artificer Dilettante III: Your knowledge of magical items 
has improved, and now extends to magical arms and armor. Also increases 
your caster level in your dilettante class by 1, so you are now treated as 
a fourth level Artificer instead of first level for scrolls and purposes.
AP Cost: 3 	Level: 15 	Progression: 53 	Requires: Improved Artificer Dilettante II

What does this mean, exactly, for UMD'ing scrolls as a rogue? Will I have a higher success % earlier, or be casting at a higher caster level as I progress? If I take these and a couple of the Rogue scroll/wand mastery enhancements (for +45% effectiveness), will I be able to function as a competent backup healer/buffbot? I know I'd still be missing things like quicken, heighten, etc. I'm planning a TR and the Artificer Dilettante appears to be the most useful to parties.

Feedback is, as always, appreciated.

Yes. You'll have a +2 UMD on whatever items are listed in the tier you have, and you'll also cast the items as if they were 1 caster level higher.

I assumed the +1 CL would also apply to potions by taking this enhancement. But I found out it does not. Anyone have thoughts/experiences with this?

Artificer dilettante on a rogue makes you the second best scroll healer in the game (after an actual artificer). +2 UMD is really nice as well. +1 intelligence is really nice for assassinate DC. Repeater proficiency is really nice for those times that you have to ranged.

All around, artificer dilettante is an excellent choice for a rogue.

Artificer dilettante on anything you plan to use scrolls from is a (Int)elligent idea. Even if you were considering a Bard (which drip of UMD to start) or anything with scroll mastery the synergy and benefit is still enticing.
