Yes, you can put drip tips on cartomizers - it's actually kind of necessary, since the rubber stoppers that come with most cartomizers tend to get a lot of condensation in the airway. There are a number of vendors that assemble basic eGo kits that come with cartos. I can think of one in in particular that comes with an eGo 650mah(standard, not twist), charger, and 5 Boge LR's for about $35.
Boge has been having some user issues more than quality issues. I continue to buy and use them without problems, myself. Now on my eGo's, I almost always use Boge 3.0 blanks. The reason for this is that the resistance swing is next to nothing. they start at 2.9ohms and end no higher than 3.1, but usually about 3.0ohms. LR's start as low as 1.8 and end as high as 2.6 (all values tested under load), which overall means that the 3.0ohm cartomizers are a much more consistent vape.
The imortant thing to remember about Boge cartomizers is that they have a fairly dense filler material, and an even more dense inner shield, meaning that after you fully saturate them for the first time, it's best to let them sit about 15 minutes before first use, and keep them topped up (or in a carto tank) for maximum life. Using as clear a juice as possible also easily adds up to 4-5 days worth of use over a darker liquid.
A Solid alternative to Cartos is atomizers, or a clearo style tank like the vivi nova. The Nova is especially nice since it also doubles as an excellent platform for getting into rebuildables. This is doubly true when considering how many bad Nova heads have been reported. General consnsus is to use 3mm silica wick and Kanthal A1 30,31 or 32AWG wire. The Nova is about the easiest rebuildable out there at the moment - especially for the price. I know this might not be an option being considered by a newer user, but it leaves room to grow later if desired, and is an overall cheap and good performing product so long as you receive good heads.
Also try to avoid anything dual coil on an eGo or similar battery, as they have a hard time keeping up anywhere above 3.8-4.0V on a twist or other similar adjustable/variable voltage unit.
HTH!
