I moved to Maynooth recently and am very happy with my decision. I like having a bigger house with more room, parking etc. I find that all the facilities I need are in the area-pubs, restaurants, shops etc, and it's a short drive from other towns, Liffey Valley etc. I normally use the train which I find very convenient and have also used the bus services on occasion. I still go out in Dublin regularly and get nitelink or taxi home. I would definitely consider Maynooth/Celbridge/Leixlip as they are all nice towns within reasonable distance of Dublin IMO.
That's all very well if you work right beside Heuston station, but if the OP doesn't then it may not be so convenient. I work in Dublin 4, and can get a train for Maynooth-Grand Canal Dock directly in the morning, and the same in the evenings. If I lived in Celbridge I would have to get a dart to Connolly, the Luas to Heuston and then the train home, which would be costly and a lot more tiring than a direct journey. My commute is around 50 minutes but I find it pretty comfortable as I don't have to change trains etc
Train commute from Heuston to Hazelhatch in Celbridge is only 13 mins in the evening. The train station will become a dart station under transport21 with 4 lines serving the city centre. This work is already underway. So it really depends on where in the cty centre you work, but I get the 6:40 train from Heuston every evening and am sitting down at home in Celbridge by 7.
